Abstract: In the present research, the electrochemical behavior of corrosion in Conventional Concrete (CC) and Sustainable Concrete (SC) made with 80% of Portland Cemment, 20% of Sugar Cane Bagasse Ash and Recycled Aggregates with 50% and 100% was evaluated, AISI 1018 steel bars were embedded in all the specimens, which were exposed to seawater for more than 300 days. For corrosion monitoring, the electrochemical techniques of Corrosion Potential (Ecorr) and Linear Polarization Resistance was used to determine the intensity of the corrosion current (Icorr). The results of Ecorr and Icorr indicate that the sustainable concrete of this study can be used in non-aggressive environments, but not in highly aggressive media such as seawater, since according to the results, its protection against corrosion is weak, with the SC having the worst performance with 100% recycled aggregate.
